SASH-HOLDER.

Specification of Letters Patent.

Application filed September 27, 1911.

Patented Oct. 2'7, 1914. Serial No. 651,537.

To all whom it may concern:

Be it known that I, STEPHEN VIRAGI-I, a resident of Swissvale, in the county of Allegheny and State of Pennsylvania, have 1nvented a new and useful Improvement in SashTIolders, of which the following is a specification.

This invention relates to windows and particularly to the devices for producing an air tight and dust proof seal or joint around the sashes and for preventing rattle and v1- bration thereof.

The object of the invention is to provide a simple attachment which can be readily applied to any window, new or old, which produces an air tight window and prevents rattle or vibrationof the sashes, and which embodies a spring which is without tension when the window is open and is placed under tension whenever the window is closed.

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

Inthe drawings, which represent one embodiment of the invention, Figure 1 is a sectional elevation, showing the lower corner of a window sash and frame with the invention applied thereto; Fig. 2 is an elevation of the inside of the sash and frame; Fig. 3 is a perspective view of a keeper mem her; and Fig. 4 is a side view thereof.

The window shown in the drawings embodies the usual frame consisting of a sill, jamb and pulley stiles, the latter being pro- Vided with heads 14, 38 to form runways for the sash. The sill is also provided with a parting head 15.

The sash 8 shown in the drawings is the ower and inner sash. although it will of course be understood that the invention may be applied to the upper sash as well as to the lower. Said sash at either or both of its lower corners is provided witha suitable wear plate 26, shown as a plate countersunk in a recess in the sash. and which cooperates with a suitable spring, such as the leaf spring 31. One end of this spring is free and when the window is open projects into the path of movement of the sash, while the other end is bent to form a loop or eye 32 to receive a securing member, such as the screw shown. The fulcrum for the spring consists of a screw or bolt 41 lying on one side of the spring and passing through an opening in one ear of an L-shaped keeper member 33, the other car of which embraces the spring and retains it in normal position with its free end in the path of movement of the sash.

The spring and keeper member and the parts for securing them to the window frame are preferably located in a socket or seat formed by omitting or cutting away a portion of the lower end of the inner bead 38 so that the spring acts on the sash at a point close to the runways in which it travels.

In operation when the sash is lowered to its bottom position, shown in Fig. 1, the wear plate or plates 26 strike the springBl which thereupon forces the sash outwardly into contact with the parting beads 14, 15 and thereby produces a perfect air tight and dust proof joint around the entire sash. The device also holds the sash by friction and entirely prevents rattle and vibration thereof.

It comprises only a few simple parts, which can be attached by anyone without special skill. and without requiring the use of special tools.

What I claim is:

In a window comprising a frame having runways and a sash slidable therein, means for forcing the sash horizontally into contact with the frame to thereby produce an air tight joint around the sash, comprising a leaf spring having one end bent to form a loop, a securing member adapted to be passed through said loop and into the frame, an L-shaped keeper member, a securing member adapted to be passed through one ear of said keeper member and into the frame on one side of said spring and in such position that the free end of the spring normally projects into the path of movement of the sash, said second named securing member forming a fulcrum for and the other ear of said keeper member lymg on the opposite side ofsaid spring and arranged to retain it in operative position.

In testimony whereof, I have hereunto set my hand.
